(e) Generation timing of compare match interrupt request signal (INTTT0CC1)
The timing of generating the INTTT0CC1 signal in the external trigger pulse output mode differs from the timing
of generating INTTT0CC1 signals in other modes; the INTTT0CC1 signal is generated when the count value of
the 16-bit counter matches the value of the TT0CCR1 register.

Note
Note The timing is actually delayed by one operating clock (fXX).
Usually, the INTTT0CC1 signal is generated in synchronization with the next count-up, after the count value of
the 16-bit counter matches the value of the TT0CCR1 register.
In the external trigger pulse output mode, however, it is generated one clock earlier. This is because the timing
is changed to match the timing when the output signal of the TOT01 pin changes.
